    Very hard to guess at stuff without data logs of it happening and a tune file.

    May want to check fuel pressure as well.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    We are wanting to know what fuel pressure is doing the whole 1/8 mile pass.
